Love your videos! Very helpful and simple. I'm in the process of making a passion project in twine, so this is perfect!

Adding one key to unlock a passage is easy, but I really can't seem to find how to add two keys. I want to have the player pick up two objects to proceed to the next pasage but all I've made is a loop. I tried using then the text and then the text and but as I said that doesn't seem to work. Is there any way for this to work?

I'm sure the information would be easy to find or deduce, but what would the command be to just "remove" a key? Say instead of there being just a value check to see if you have one or two of "key" you go through a passage that removes a key from having two to one. OR is this explained in your other video "Improving keys and doors?"

One way to approach it would be to change the value of the $key variable at the start of different passages to decrease it.
Alternatively, although more complicated, $key could be an array of multiple keys and its length decreased based on removing entities.
